Suggests a method treating geometric optics using a microcomputer to do the calculations of image formation. Calculations are based on the connection between the composition of lenses and the mathematics of fractional linear equations. Logic of the analysis and an example problem are included. (JM)

Describes a microcomputer-controlled system which determines the current/voltage characteristics of a resistor, lamp, and diode, detailing system elements, construction, and providing printout of the program developed to provide control and arithmetic functions necessary to complete the experiment. (SK)

Microprocessor-based student experiments are described, including flowcharts of a typical program for time interval measurement and experimental and measurement subroutines. (JN)

Describes apparatus, computer program (for Apple II), and procedures used in an experiment to determine the velocity of sound in air. In addition, the experiment focuses on the attention required in calibrating equipment and the measuring of both long distances and very short time intervals. (JN)

Describes the use of microcomputers in data acquisition and simulation of physical phenomena. Discusses digital and analog inputs/outputs, simulations, and interactive programs in mechanics. Includes examples of computer programs. (SK)

A computer program, making use of interactive computer graphics, has been developed to help students become fluent in the mathematical procedures needed to understand concepts of addition of waves. Background theory, use of the program, and technical and educational features of the program (written in Fortran) are discussed. (Author/JN)
